R21 Review

Hardware
1

I have been using the R21 Refoss dual channel rele and It works pretty nice. Since the last firmware update to the 1.1.9 the error where consumption energy was not being registered is being fixed.

It is quite similar to the Shelly overview of the functions that they offer but still seems a device very promising.

The double use of it as a dual channel rele and the cover automatization is awesome. It allows quite good precision of the % of aperture of the cover and works quite fast.

As always, I would love to see the integration to apple home kit of the device, but it seems very promising.

Any ideas aside of this?

Joined just for a Refoss commercial ? There are a lot of these recently.
Edit:
Strange there are a lot of ‘volunteers’ popping up who out of nowhere post a topic how good their Refoss device is. Something fishy is going on.

I have been looking at the Shelly, but in what areas are Refoss R21 any better?
I can not really see the benefits.
